From: Alan Cox Date: Mon, 22 Jun 2009 17:43:18 +0000 (+0100) Subject: msm: fixups to match current code X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=44da59e4006fbf7c4cc9b54485a37a40726091ee;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git msm: fixups to match current code The tty layer is now a bit more fussy about reporting the right baud rate back. Make the msm driver match the current state of affairs.
